I have read several books of personal development (quantum, spiritual, law of attraction) and I am confident he is the best (next to "Letters of Christ"). For those who have ever read a book containing the teachings of Abraham, they will find here a comprehensive guide that takes a ride on all aspects of life and how to improve them. If you do need to keep only one book for your hardware quest, spiritual, professional, relational and personal, the book (or CD of the same title) is a must. For what does not have much time for reading, buying the audio book (CD) and you can listen and listen again home, car, office. You will transform you, sometimes without realizing it immediately and you will find yourself smiling at some events. And do not forget to say thank you every time you get what you asked or when you perceive the signs.
